1% (presumably m/v) glucose solution would contain 1 g of glucose per 100 ml of solution. Therefore the conversion of 1 g / 100 ml to units of mol/L requires that we divide by the molar mass and multiply by the conversion factor of ml to L. Therefore: (1 g / 100 ml) * (1 mol / 180.16 g) * (1000 ml / 1 L) = 0.0555 M = 0.06 M.

Which formula do you use for the calculation of absorptivity?
ANSWER:"e is a measure of the amount of light absorbed per unit concentration".Molar absorbtivity is a constant for a particular substance, so if the concentration of the solution is halved so is the absorbance, which is exactly what you would expect.The formula for the molar absorptivity is given as followings:A=ecle=A/cle = the molar absorptivitywhere A is known as the A is known as the absorbance, l measures the length of the solution the light passes through,c is theconcentration of solution in mol /dm^3.Remember that the absorbance of a solution will vary as the concentration or the size of the container varies. Molar absorptivity compensates for this by dividing by both the concentration and the length of the solution that the light passes through. Essentially, it works out a value for what the absorbance would be under a standard set of conditions - the light travelling 1 cm through a solution of 1 mol dm-3. a
How much do you determine the molarity of a solution of 10 grams of NaOH in 500 mL of solution?
To convert to per litre we multiply weight by 2. This gives 40 grams per litre. 40g divided by 40g/mol is a 1 molar solution.
How many milligrams is 40 micro-moles of glucose?
Answer: 7 x 10-3 g glucoseProcess below:First convert 40 µmol to moles. 1 µmol = 1 x 106 mol.40 µmol x (1 mol)/(1 x 106µmol) = 4 x 10-5 molMultiply 4 x 10-5 mol by the molar mass of glucose (180.156 g/mol).4 x 10-5mol glucose x (180.156 g glucose)/(1 mol glucose) = 7 x 10-3 g glucose
How many grams of solute are dissolved in a 500.0 mL sample of 0.50 M magnesium iodide?
Molar mass of Magnesium Iodide=151.2g/mole 1 Molar solution=151.2g/L 0.5 M solution=75.6g/L=75.6g/1000mL=37.8g/500mL
What are the 3 factors that affect how quickly diffusion occurs?
Relative molar mass, temperature, and concentration difference/gradient.
Calculate the isotonic coefficient for NaCl if a 07M of NaCl solution equaled the hemolysis of14M glucose solution?
i = isotonic molar [glucose] / isotonic molar [NaCl] i = 14 M / 7 M = 2 i = isotonic molar [glucose] / isotonic molar [NaCl] i = 14 M / 7 M = 2 i = isotonic molar [glucose] / isotonic molar [NaCl] i = 14 M / 7 M = 2 i = isotonic molar [glucose] / isotonic molar [NaCl] i = 14 M / 7 M = 2
How do you make a Molar solution from 32 percent hydrochloric acid?
To make a molar solution from a 32% hydrochloric acid solution, you would need to first calculate the molarity of the 32% solution. Molarity is calculated by multiplying the percent concentration by the density of the solution and dividing by the molar mass of the solute. Once you determine the molarity, you can then dilute the solution to the desired molar concentration by adding the appropriate amount of solvent (usually water).
What is the concentration of the solution in nano molar units?
The concentration of the solution is measured in nanomolar units.
Is molarity synonymous with molar concentration?
Yes, molarity and molar concentration are synonymous terms used to describe the concentration of a solute in a solution.
What is it called when the concentration of a solution defined in terms of moles of solute per liter of solution?
This is a molar concentration.
How much glucose powder in 0.5 L of water for a 1 molar solution?
To make a 1 molar solution of glucose in 0.5 L of water, you would need to dissolve 90.1 grams of glucose powder. This is because the molar mass of glucose (C6H12O6) is approximately 180.2 g/mol, and for a 1 molar solution in 0.5 L of water, you would need 1 mole of glucose, which is 180.2 grams.
What is the molality of 7.80 percent by weight glucose solution?
To find the molality of a solution, you need the mass of the solvent (usually water) in kilograms and the number of moles of solute (glucose). Given that the solution is 7.80% glucose by weight, you can calculate the mass of glucose in the solution and then convert it to moles using the molar mass of glucose. From there, you can find the molality by dividing the moles of glucose by the mass of the solvent in kilograms.
What is the molarity of a solution with a percent concentration of a given solute?
To find the molarity of a solution with a percent concentration of a solute, you need to know the molecular weight of the solute and the density of the solution. Then, you can use the formula: Molarity (percent concentration density) / (molecular weight 100).
What is the molar concentration of nitric acid?
The molar concentration of nitric acid can vary depending on the specific solution. However, a common concentration of nitric acid used in laboratories is around 16 M (molar). This means there are 16 moles of nitric acid in 1 liter of solution.
What is the molar concentration of 80 g of glucose dissolved in sufficient water to make 2 L of a solution?
The equation to find molar concentration is C= n/v (concentration= moles/volume). For 80g of glucose, you would first need to find the number of moles; n= m x mm (moles= mass x molar mass). Then you can input that number into the equation C= n/v.
What is the difference between normal and molar concentrations in a solution?
Normal concentration is expressed in terms of equivalents of a substance per liter of solution, while molar concentration is expressed in terms of moles of a substance per liter of solution. The difference lies in how the concentration is calculated and represented in the solution.
What is the difference between molar concentration and molarity, and how do they relate to each other in the context of solution chemistry?
Molar concentration and molarity both refer to the amount of solute in a solution, but they are calculated differently. Molar concentration is the amount of solute divided by the total volume of the solution, while molarity is the amount of solute divided by the volume of the solvent in liters. In solution chemistry, molarity is commonly used to express the concentration of a solute in a solution.
